This area encompasses the study of astrophysical objects and events outside of the Milky Way. Due to the finite speed of light, looking farther away also means looking at times when the Universe was younger. In this area we primarily study galaxies across a large fraction of the history of the Universe. More specifically, we are leading researchers actively studying a number of topics. These include accreting supermassive black holes at the centers of galaxies, objects known as quasars or AGN, from nearby ones to those in the early Universe, and from those barely accreting to those with the highest gas accretion rates. It also includes the ISM and stellar populations of galaxies in the early Universe as well as in local galaxies, including those magnified by strong lensing. For our studies we use a large range of observatories including the ground based ALMA, VLA, VLT, Magellan, Gemini and CTIO, as well spaced based telescopes like HST, JWST, XMM-Newton, NuSTAR, Swift and Chandra. We are also working on current and upcoming large projects, such as SDSS-V, Rubin LSST and 4MOST.
